T2 Deck Nightmare Vortex Opnion.

T2 Deck Nightmare Vortex Opnion.

Im building a Nightmare-Vortex survivor deck. This is how it will eventually look like.

Ambre
Kolos
Ghumbo
Estalt
Nistorok
Oshitsune
C beast
C wing

I was wondering how this deck would theoretically fare in T2 Survivor.

Also any suggestions to replace which card to make this deck better would be appreciated.
I have all the Nightmare cards, and am building up my vortex right now, And have a budget of around 20 000 clintz.
So if there is a better suggestions, could anyone give me ideas on which card i would replace to get better results
